The summer sun and buns are out -- burger, sandwich and hot dog buns, that is! Geoffrey Zakarian starts by sharing his tips for a moist and flavorful Mushroom Turkey Burger. Katie Lee makes a meatless Grilled Halloumi Sandwich with Watermelon Relish, and Sunny Anderson puts her amped-up meatloaf between two buns for her Meatloaf Burgers. Then, Alex Guarnaschelli elevates a traditional hot dog with her Hot Dogs with Mustard and Relish, and Jeff Mauro shares a burger from his neck of the woods, his Northwest Indiana-Style Smashed Burger. Finally, Geoffrey and his wife, Margaret, make a Boozy Cherry Milkshake that pairs perfectly with any burger or hot dog.
